Serious problem cat won`t eat and barly drinks. tried everything from vet to 550 dollars in xray and test?

The vet is wrong,,there is SOMETHING wrong with the cat. First of all i would get all blood work copies and xrays and take them to another vet,,these are things you wont have to pay for over again. You will just have to pay the office visit. Run do not walk to another vet. Is she eating?...if not she needs fluids NOW. Don't offer to pay someone here for advice,,take the cat and pay another vet>>>QUICKLY..you are the only one that can save her.
